I'm currently reviving glibc port for xtensa and both TLS-related issues
for which I sent patches for uclibc-ng were triggered by the nptl/tst-stack4.
This test is not (and apparently never was) present in the uclibc-ng test
suite. However it's big, it doesn't complete in reasonable time on
configurations that I have, so I made a small version of it which I can share.

I really don't know, I'm just going through the testsuite failures, fixing
glibc port and checking corresponding bits of uclibc-ng port. I have ~50
more failures not related to math and a few hundreds more of math
related, so it will probably take me several weeks to complete.
